LUBRICYAQTILJNG enames.-

To all whom it may concern Be it known that I, FRED KOIJLMANN, a citizen of; the United States, residing at Greene, in the; county of Butler and State of Iowa, have invented awnew and useful Lubricating Apparatus, of which the fol- I lowing is a specification. 7

his invention relates to certain improvements in beaters such as used in connection with some types of threshing machines wherein a number of finger carrying shafts V are mounted for rotation about individual shafts while rotating collectivelyabout the axis of a main shaft. :Where a number of rotating shafts are moved at a high speed about a fixed axis, as in the beatersmentioned, it has been a slow and laborious undertaking to lubricate all of the shafts 111 machines of the type described and and has necessitated long delays in theoperation of thebeaters.

One ofthe objects of the present invention is to provide simple and eflicient means whereby a lubricant can be supplied to the various bearings while the mechanism is in operation.

Another object is to provide lubricating mechanism which can be installed readily which are already in use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood thatvarious changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claims.

In the accompanying drawings the pre- 7 ferred form of the invention has been shown.

In said drawings 7 Figure 1 is an elevation of a thresher beater of the type mentioned and having the present improvements applied thereto, the central portions of the gang of finger shafts being broken away.

Fig. 2 is an enlarged section through one of the heads of the beater, said section being taken on the line 2-2, Fig. 4

Fig. 3 is a transverse section through a portion of one of the heads, said section being taken on line 3-3, Fig. 6.

Fig. 4 is an end elevation of the beater,

g V Specification of Letters Patent. Patentedlsept. 17,1918. Application filed May is, 1918. r

Fig-5 is a section through one of the" lieadswitli the cover parts being broken away.

Fig. 6 is an elevation of the the cover plate removed, certain plate and showing the-means-employed forc0nducting a lubricant to the bearings of the gears.

Referring to the figures by characters of reference, 1 designates portions ofa thresher structure provided with stationary'bearings 2- and 8 in whichtheiinain shaft 4 of the beater is mounted for rotation: A gear 5 is coupled to the inner side of bearing 2, as shown in Fig. 2, r

so as to "be held against rotation and this gear may be provided with a boss 6 extend-- the centerof" mg into an openingformed in the cover plate 7 of one of theheads of the beater. The heads of the beater, which have bee'n'i'ndicated at 8 and 9 are preferably circular and hollow, ing lubricant receptacles having peripheral openings normally closed by screw plugs 10 or the like. By removing these plugs the lubricant can be placed in the respective heads.

Each of the heads 8 and 9 has an interior hub 11 which is keyed or otherwise secured to the shaft 4: so that the two heads will ro tate together with the shaft.

Journaled in the peripheral portions of the heads 8 and 9 are parallel shafts 12, there being bearings formedin the heads for these shafts, as shown at 13. Leading to each of the said bearings is a feed tube 14:, all of the tubes being arranged radially within their heads and having the advancing portions of their inner or free ends beveled as shown at 15. Beaterfingers 16 are mounted on the shafts 12 in the usual manner; The shafts 12 are extended through the cover plate 7 of the head 8 and are provided with gears 17. These gears, in turn mesh with intermediate gears 18 which are secured to stud shafts 19 journaled' in the cover plate 7. Wings 20 are extended outwardly from the hub 11 in head'8 and are secured to the cover plate at their outer ends by bolts 21 or in any other desired manner. The forward or advancing faces of these wings are grooved as at 22, said grooves leading to the hearings in which the the chambers therein forinthe heads 8 and will all be rotated about the axis of sald of the tubes Thus the. sfipalfate 9 and the finger shafts shaft 4 and the gears will cause the shafts 12, at the same time, to rotate about their individual axes. This operation is conr mon'tobeaters of this type. The advantages in the present structure, however,'are that during the above described operation, lubricant contained in the two heads will be gathered up by the adv ncingbeveled.ends l4: and directed outwardly by centrifugal force to the bearings of the shafts At the salnetime a portion of the head-8 will; be.
